Tom Izzo tried to make his old high school basketball team feel at home when it played in the state semifinals at the Breslin Center. His gesture reportedly resulted in an NCAA violation.

In March, Izzo’s old high school, Iron Mountain, made a trip to the semifinal round of the state tournament for the first time in school history. Since the game was played at Michigan State’s Breslin Center, the Spartans’ head coach gave his alma mater a tour of the facility, and allowed them to watch a practice.

A few days later at the B1G Tournament, Izzo talked about the tour briefly, which led Michigan State to self-report and NCAA rules violation.

Per MLive.com, Izzo’s tour violated NCAA rules about coaches having contact with potential recruits. The NCAA does permit high school athletes to tour facilities and speak with coaches if the facility is not being used to play a game. The tour was given one day prior to Iron Mountain’s semifinal game, triggering the NCAA violation.

MLive.com reports that the violation mentions that Izzo was unaware of the nuance in the rule. It also mentioned that Michigan State is not currently recruiting any players from Iron Mountain High School.

There were no self-imposed penalties stemming from the violation.
